Application filed June 19, 1911. Serial No. 83,924.

To all whom it may concern:

- Be it known that I, CARL Brssnrm, of-

new and useful Means for Attaching Electrical Appliances to Conduit Outlet- Boxes, of which the following is a specification.

This-invention has for its object the productionof means for attaching electrical 1o appliances to conduit outlet boxes; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views. Figure l is a plan of-onc form of conduit outlet box provided with a preferable construction of my invention. go 7 Fig; 2 is an elevation, partly in section, of

a conduit outlet bOX'PIOYldGd with my invention, an electrical appliance as a lamp socket being shown attached thereto.

Fig. 3 is a longitudinal sectional view :5 taken at a right angle'to Fig. 2.

Fig. 4 is a plan of the attaching means. a 1 is the conduitoutlet box which may be of any desirable form,-size and construction, such box beingdie're shown as having an 3Q opening 2 in one side thereof and one or l more internally threaded nipples 3'by means of which conduits containing electric wires are connected to the box 1.-

The-means for attachi g the electrical aps s pliance to thebox 1., comprises a body for;

en' aging-one "face of the margin 4 of the wal around the o ening 2, and having 'means fixed relative y thereto for engaging the opposite face of such margin and also additional means spaced apart from the former' mcans, the additional means being hmoysilaly carried'by the body and movablefi tof'and' out of -'intei-locking engagement .W 1th such opposite faceoifih'e margin 4. V

The body 5 is preferably annul'ar in general outline and engages the outer face of the-margin -4 and is provided with fixed meansfo yengaging the inner face of a porf ition'ot said margin. The fixed means en- 5 O1, gflge S the-margin at at separated po nts" i '-.located' man are concentric-with the center of thebo'dy 5, and is here shown as a pair of liigs 6 looted on one side of a. diameter, of, the? body, the lugs 6 being offset from the i body 5 and preferably formed integral .the space between said lugs.

- en age therewith. T he movable means is located on the (gpposi 1e side of said diameter-equidistant rom :Laid lugs and engages the opposite ortion of the margin irom that engnged by the lugs. Said movable means 0| comprises a sc rew 7 arranged radially with the center 0; the bodv 5 and threaded throu h a lug 8 integral with the body 5 and exten ing inwardly through the opening 2-, Z the said lug 8 being preferably arranged 6i substantially opposite to a point midwaybetween the p iir of lugs 6 but spacedapart. from the pair at lugs a distance greater than that between the members of said, pair oi lugs (i substan .ially as shown'in Fig. 4. The pair of lugs 3 act to holdrthe body rigid from lateral c isplacement in case the screw 7 is loose, and are the equivalent of a sin gle lug of the same extent as the lugs 6 and The body in also formed w1th= iiiwai dly extending', and diametrically-disposed membecs 9 arrangi d in a plane substantially intermediate heiween the lug 8 and the'menfl bers of the pair of lugs 6 and formed with a plurality oi pairs of screw holes 10, the

holes of each pair of which are spaced the 'proper distar cc to receive the fastening screws as 11 win commercial electrical ap-. plianee, it beii g understood that such screws in different makes are spaced different distances apart. '-The electrical appliance is heresh-own as a lamp socket ll.

In placing :his' attaching, means in" posi tion on thecondu'it' outlet box, "the body 5 99 i of said meant is positioned to rest on the margin of ti wall around the opening of the outlet box with the lugs 6 extending'um der and engng ng the inner face of'such marq in', the screw 7 18 then turned so that .will their ner face of said. margin as i j shown inFigzB'.

What; claim is; I

1. Q1112; eoml inati duit, and an opening throughllone'side ;of,.

and 'with the major portion, of the; underside of said ap pliance in uninterrupted coma munication with the cha'mbenin the "box through said ipening, said meanscom risinga flat rinig'seated upon the face 'o the ,110

- m e-pee box haying m gan'sfor connection t con: 9 r

box surroundin the opening therein, said ring having a ooh-shaped lug projecting from the inner edge thereof, and extending inwardly and outwardly for. engaging the inner marginal wall of said opening in the box, asecond lug extending from the inner edge of the rin at a point substantially opposite to the rst lug, a screw adjustable transversely therein anddesign'ed to engage edge of t stantiall intermediate between the lugs, and

- cation with the chamber in thebox throu h.

with the aforesaid marginal wall, and parts projecting from oppositesides of the inner e ring, and locate in a plane subprovide with openings for receiving means for securing said applianceto the ring, said ring and appliance constituting a closure for ,theopening in the'box,'substantially as and for the purpose described.

2 The combination witha metallic outlet box having means for connection to a conduit, and anopening through one side of relatively large area, and an electrical applianoe located outside of the box, of means for securin the base of the appliance to'the side of the x ro'vided with said 0 enin and with the ma or' portion of the un er si e of said appliance in uninterrupted communisaid opening, said means comprising a at ring'seate'd, upon the face of the box sur-- rounding the opening therein, said ring having a pa r of spaeedapart hook-shaped lugs projecting from the inner edge thereof, and extending inwardly and outwardly for engaging the inner marginal wall of said 0 ening in the box, a third lug extending rom the inner edge of the ring at a point substantially opposite to a oint mldwa between the pair of lugs, said third lug eing spaced apart from the pair of lugs a dis tance greater than that between the members of said pair, a screwadjustable-transversely in the third lug and des gned to engage wit thevaforesaid marginal-wall, and parts projecting from diametrically opposite sides of the inner edge of the ring, and located in a plane substantially intermediate between the third lug and the members of the pair of lugs, and-provided with openings for receiving means for securing said appliance to .the ring, said ring and appliance constituting a closure for the-opening in the box,

substantially as and for the purpose, de-

-scribed.

In testimony whereof, I have hereunto signed my name, in the presence of two'at testing witnesses, at Syracuse, in the county of Onondaga, in the State of New York,
